Book Description
The United States registered phenomenal economic growth between the establishment of the new republic and the end of the Civil War. This study argues that the transition of the United States from an agrarian economy in 1790 to an industrial leader in 1865 relied fundamentally on the spread of technological knowledge within and across industries.

Book Description
Human communication has traditionally revealed important aspects of identity such as gender, age and race. However, such information is now often masked by computer-mediated communications. This text examines the various ways modern technology is challenging conventional notions of gender identity.

Book Description
According to the classical theory of functional structure of bone which was developed by J. Wolff (1884, 1892) and W. Roux (1895) following the investigations of the functional architecture of the substantia spongiosa by H. von Meyer (1867), bone is "functionally" laid down in gross form as well as in minute architecture in accordance with the "maximum-minimum-law". As a result of functional adaptation, a maximum of efficiency is achieved with a minimum of material (Kummer, 1962a). In this sense functional adaptation is a reaction of adaptation of the idiotype-within the bounds of the reaction norm-to a changed internal environment, that is in this case an adaptation to changed mechanical stresses. 1. The Formation of the Normal Femur Shape The heredity basis of shape characteristics of human femora is really unknown. Identical twins show a significant lower variability of length of femur than binovular twins. Population variability of length of femur due to heritability may exceed twice the variability due to environmental factors (Knussmann, 1968). A significant part of the total variation of femur shape characteristics remains therefore unexplained supposing that the sources of variation due to heritability and environmental factors are also nearly the same for the other traits.

Book Description
Millions of trees live and grow all around us, and we all recognize the vital role they play in the world’s ecosystems. Publicity campaigns exhort us to plant yet more. Yet until recently comparatively little was known about the root causes of the physical changes that attend their growth. Since trees typically increase in size by three to four orders of magnitude in their journey to maturity, this gap in our knowledge has been a crucial issue to address. Here at last is a synthesis of the current state of our knowledge about both the causes and consequences of ontogenetic changes in key features of tree structure and function. During their ontogeny, trees undergo numerous changes in their physiological function, the structure and mechanical properties of their wood, and overall architecture and allometry. This book examines the central interplay between these changes and tree size and age. It also explores the impact these changes can have, at the level of the individual tree, on the emerging characteristics of forest ecosystems at various stages of their development. The analysis offers an explanation for the importance of discriminating between the varied physical properties arising from the nexus of size and age, as well as highlighting the implications these ontogenetic changes have for commercial forestry and climate change. This important and timely summation of our knowledge base in this area, written by highly respected researchers, will be of huge interest, not only to researchers, but also to forest managers and silviculturists.

Book Description
Investigations on anatomical specimens have demonstrated that the subchondral mineralization does indeed show regular distribution patterns from which conclusions about the mechanical situation within an individual joint may be drawn. Since radiographical densitometry and histological methods are only available for determining the adaptive reaction of the bone to the mechanical situation in a joint after death, the information obtained applies only to an end situation and tells us nothing about the development of the changes with time. Furthermore, investigations carried out on human specimens by radiographical densitometry mostly apply to samples of a particular age, since such specimens can be acquired only from departments of pathology, forensic medicine or anatomy.
